Portable Power

Hi everyone, inspired by the Modular on the Spot series, I'm in quest for a portable power solution for limited outdoor use. I basically just want to run a solo Tiptop Mantis for 10-20 minutes, primarily to film some drone pieces. Have no clue where to start, could something like this do the trick... http://a.co/d/24ycg66

Thanks!

I haven't tried this myself but for such a short duration and assuming you intend to just replace the normal AC power brick with a 12v output battery, I'd go with something much cheaper?

Maybe this one as a guess, only $30 shipped!

EDIT: This one has twice the mAh plus a 5v USB outlet as well for only $4 more:

I often run a small modular rig in my RV from the 12 leisure batteries, feeding the 12v direct into the DC input of a uZeus.

Provided the Leisure Batteries are fully charged, they'll power the uZeus for several hours.

Fully charged the leisure batteries will be putting out over 13.5v this drops over time and when it reaches around 13v the -12v rail of the uZeus will start to fail, followed a while later by the +12v.

Mmmmmmm... Watching with interest...

My only input for now would be that I asked a busker, earlier in the year, how was he powering his amp and effects units. He uses 12v lead acid batteries and an inverter. Might sound a bit daft going from 12v DC up to 240v AC and back down to 12v DC but I guess it takes away the uncertainty of the DC voltage.

One other consideration is that if you intend to fly somewhere then I think that there are limits as to what you can take on a plane when it comes to lithium-ion batteries.

went to the airport a day before the flight to check with security services and police. they said "no problem" and indeed there was no problem, neither on the flight from switzerland to thailand nor back.

Indeed, the battery you link to is a sealed lead/acid battery and there are no restrictions on those at the moment other than they cannot leak.

The airline restrictions are only for lithium-ion batteries:-

Anything above 10Wh and things start getting a bit tricky...
